Good morning, I'm David Greene. Yesterday, a Twitter hashtag threw fans of Cher into a panic. It read: #nowthatcherisdead - all one word - referring to the late British leader. But many read it as "now that Cher is dead."

One fan of the singer tweeted: I note the hashtag #nowthatcherisdead is trending. I can't confirm anywhere that Cher is dead - leading other users to tweet advice such as why hashtags need spaces.
